What a wonderful Easter Chapel service we had at School led by Year 12 reading the Easter story from the Gospel of John. The singing from the whole School was inspira- tional, supported so ably by our instrument group. It was wonderful that so many parents and family members could Term 1 Issue 1 share this occasion with us. April 2016 The purpose of this newsletter is to review the term that is almost over and to let you know some important dates for the first half of Term 2. TERM ONE IN REVIEW Parent/Guardian Information Nights Your feedback on these occasions was that we have been able to convey the School expectations and guidelines in supporting learning at home. The attendance this year was very good. We see these occa- sions as vital in creating the link between School and home. The Senior Hospitality students excelled in catering for us on all these occasions. I am sure you will agree! Module Two (Years 9 & 10) School Camp What a varied week with the most magnificent weather on the South Coast. Our students were able to complete field trips for Geography, Science, Business and Commerce, as well as strenuous activities such as climbing Pigeon House Mountain and canoeing the Clyde River from Nelligen to Batemans Bay. One of the field trips was a visit to a dairy farm where all the cows are milked by robots! This is a new project in the Nowra district and an amazing application of current technology to agriculture.

In a period of two weeks most of the southern section of the Reserve including the whole of the Kelly wilderness area was consumed. The long drought and hot summer eventually took its toll of the Reserve. We know from past experience that periodic fires are one of the natural forces which have shaped the Australian bush and helped to produce our distinctive flora. This realisation does not, however, lessen the shock in seeing the Reserve blackened and burnt, seemingly stripped of all life forms. With rain the Reserve will recover and the mountain slopes and plains will again; be covered in their distinctive trees, shrubs and wild-flowers. As we wait for nature to take its course let us use this opportunity to take stock of the problems facing the future management of the Reserve so that we can make a fresh approach to the solution of some of the problem areas. One of the questions which must be addressed fairly quickly is the future of the Gudgenby pine plantation; the fire largely destroyed this plantation and it probably now has little or no commercial value. The remains of the plantation should be removed and the area allowed to regenerate naturally.

Some responsibility does lie with club members to help support the workings of the Council as the Canberra Bushwalking Club has been a member of the Conservation Council of the South East Region and Canberra for many years. Areas where Club members could direct their energies are: 1/ Assistance with the Kingsley Street Markets on the first Sunday of every month. This involves at most a few hours on the morning of the market helping to direct store-holders, set up tables and help with refreshments. Contact Chris Scott 477808. 2/ The urban planning working group is currently focusing on Civic's transport problems and the Murrumbidgee corridor plan. It sounds as if they could do with some more support in presenting conservation considerations to the NCDC. etc. Contact Chris Lawrence 467243(w). 3/ The forestry working group is putting a great deal of effort into the anti-woodchip struggle.

  • The Scale Transition: Scaling up Population Dynamics with Field Data
    Ecology, 87(6), 2006, pp. 1478–1488 Ó 2006 by the Ecological Society of America THE SCALE TRANSITION: SCALING UP POPULATION DYNAMICS WITH FIELD DATA 1,3 2 BRETT A. MELBOURNE AND PETER CHESSON 1Center for Population Biology, University of California, Davis, California 95616 USA 2Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, Arizona 85721 USA Abstract. Applying the recent developments of scale transition theory, we demonstrate a systematic approach to the problem of scaling up local scale interactions to regional scale dynamics with field data. Dynamics on larger spatial scales differ from the predictions of local dynamics alone because of an interaction between nonlinearity in population dynamics at the local scale and spatial variation in density and environmental factors over the regional population. Our systematic approach to scaling up involves the following five steps. First, define a model for dynamics on the local spatial scale. Second, apply scale transition theory to identify key interactions between nonlinearity and spatial variation that translate local dynamics to the regional scale. Third, measure local-scale model parameters to determine nonlinearities at local scales. Fourth, measure spatial variation. Finally, combine nonlinearity and variation measures to obtain the scale transition. Using field data for the dynamics of grazers and periphyton in a freshwater stream, we show that scale transition terms greatly reduce the growth and equilibrium density of the periphyton population at the stream scale compared to rock scale populations, confirming the importance of spatial mechanisms to stream-scale dynamics. Key words: heterogeneity; nonlinear dynamics; scale; spatial ecology.
